Demonstrators clashed with riot police in Caracas on Thursday after a march against the arrest of two opposition mayors accused of failing to stop violence in protests that have rocked Venezuela. Some 3,000 people had rallied against the socialist government of Maduro before a subgroup of protesters threw rocks at police who responded with tear gas and water cannons.
